UNITED STATES FRED BROWN, OF PATERSON, NE\V JERSEY, ASSIGNOR TO JOSEPHWADS- \VORTII, OF PATER PlCKER-OPERATING MECHA SPECIFICATION formingpartof Letters Application filed January 15, 1902 T (LZZ whom it nutyconcern:

Be it known that I, FRED BROWN, a citizen of the United States, residingat Paterson, in the county of Passaic and State of New Jersey, haveinvented certain new and usefulImprovements in Picker-OperatingMechanism for Swivel-Looms, of which the following is a specification,reference being had therein to' the accompanying drawings.

This invention relates to swivel-looms in general, but more particularlyto the picking-sticlcoperating mechanism thereof.

The object of my invention is to provide an automatic and intermittentpicking-stick- I5 operating mechanism, whereby the shuttle may be shotthrough the shed at any desired time or interval during which theswivelrack is not in operation, the operation of the picking-stick beingcontrolled and regulated from and by the head-motion of the loom. Forinstance, the shuttle and the rack may be operated alternately, or theshuttle may be made to miss two or more picks during the operation ofthe rack, according to the number and arrangement of balls in theheadmotion.

The invention consists of a sliding shoe located normally in the path ofthe pickingballs and being operatively connected with the picking'stickand operative connections between the sliding shoe and the head-motionof the loom to withdraw the shoe from the path of the picking-balls whenrequired and for any period desired.

In the drawings, in which similar letters of reference indicate likeparts, Figure 1 is a side elevation of a portion of a loom, showing myimprovements applied thereto, the picking-balls being about to engagethe shoe 40 to operate the picking-stick, which is shown in its normalposition. Fig. 2 is a similar view, but showing the sliding shoe inanother position or withdrawn from the path of the picking-balls by thehead-motion,to which the shoe is connected, the picking-stick beingstill in its normal position, the swivel-rack meanwhile being permittedto operate. Fig. 3 is a similar view, but showing the sliding shoedepressed by the engaging picking-balls and operating the picking-stick.Fig. i is a SON, NEIV JERSEY.

NISM FOR SWlVEL-LOOMS.

Patent No. 701,534, dated June 3, 1902.. Serial in. 89,801. (No model.)

tion and arrangement of my shoe, the block in which it slides, and thesquare shaft to which the said blockis secured. Fig. 5 is an endelevation of a portion of a loom, showing my invention applied theretoand the construction thereof; and Fig. 6 is a plan View of a portion ofa loom embodying myinvention.

Enough of the loom is shown, it is thought, to illustrate and explain myinvention, certain parts that are old and common. in loom constructionsbeing omitted. Any suitable spring attachment may be secured to thepicking-stick to hold it in its normal position. In the drawings, Arepresents aportion of a loom-frame, in which is journaled the shaft Fin bearings f, the square shaft D in bearings d, and the picking-shaftc. On the picktug-arm of the shaft 0 are located suitable picking-ballsG. On the square shaft D is secured the lever-arm E, which is connectedwith the picking-stick E by the lug-strap e. In the shoe-block B, whichis mounted on the square'shaftD, the shoe B is fitted to slide and iskept normally in the path of the re volving picking-balls O by means ofthe expansion-spring b. The picking-balls in retating-engage the curvedside of the shoe, depressing the same, thus causing the square shaft D,to which it is secured, to turn in its bearings and by means of thelever-arm E and the lug-strap e to operate the pickingstickE. In Figs;1, 2, and 3 the lever E, which is secured to the rock-shaftD, as shownin Fig. 6, is shown broken away to avoid confusion of lines in saidfigures. If not so broken off, it would seem to meet the lines of theshoe-block B, in which the sliding shoe B reciprocates. When thepicking-balls engage the sliding shoe, the shoe and the block in whichit is mounted are depressed, thus turning the rock-shaft D and by thesaid lever E actuating the picker-stick E. It will be seen by referenceto Fig. 6 that the said lever E is secured to the square rock-shaft'D atquite a distance from the shoe-block B, and if. the said lever were notbroken awayin the first three figures of the drawings that would notappear to be so. On each end of the shaft F is secured a lever F, eachof which is connected View, partly in section, showing the construcwitha shoe B by a chain G or some other suitable device. A lever F is alsosecured to the shaft F and is connected with the headmotion of the loomby means of a chain H or its equivalent, whereby said shaft is caused toturn in its bearings and withdraw the shoe B from the path of thepicking-balls O. This is accomplished by the head-motion pulling thechain I-I upwardly, the lever F turning the shaft F, causing the lever Fto pull on the chain G, thus causing the shoe B to slide in theshoe-block B until it is out of the path of the picking-balls O, asshown in Fig. 2 of the drawings.

The chain G passes from the lever F over a pulley device f to the shoe,to which it is secured in any suitable manner. In the drawings saidchain is shown secured to a hole 6 in the bolt 19 which passes through aslot 1) in the shoe-block B and into the shoe, where it is held by awasher and nut; but I do not wish to limit myself to these details ofconstruction, as any suitable way of causing the shoe to move in theslide or race I) of the shoeblock B until it is out of the path of therevolving picking-balls maybe adopted without departing from the scopeand intent of my invention.

As my sliding shoe is operated by the headmotion of the loom,theoperation is automatic and intermittent and the number of balls in thehead-motion will regulate the time when and the length of time duringwhich the shuttle and rack,respectively, shall in their proper turn bein operation.

With this description of my invention,what I claim is- 1. In aswivel-loom, the loom-frame, a rockshaft mounted therein, apicking-stick pivotally secured to said frame, a lever-arm secured tosaid rock-shaft and a lug-strap connecting said lever and picking-stick,in combination with a shoe-block also secured to said rock-shaft andhaving a raceway therein, a shoe adapted to slide therein, a spring tohold said shoe in its normal position, and means for temporarilywithdrawing and holding said shoe from and out of its normal position,substantially as set forth.

2. In a swivel-loom, a rock-shaft, a shoeblock secured to same andprovided with a raceway therein, in combination with a shoe adapted toslide therein,rneans therein to hold said shoe normally in the path ofrevolving picking-balls,and means for temporarily withdrawing andholding said shoe from, and out of its normal position, substantially asset forth.

3. In a swivel-loom, the combination with the picking-shaft,provided'with a pickingarm carrying picking-balls, of the rock-shaft, ashoe-block secured thereto having a raceway in it and a sliding shoeadapted to reciprocate therein, means to hold said shoe normally in thepath of the picking-balls to rock the rock-shaft and means fortemporarily withdrawing and holding said shoe from, and out of itsnormal position, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

. FRED BROWN.
